Dept. of Health, Amended 9/15/2004 Eagle County Regulations for Individual Sewage Disposal Systems (ISDS) Infiltrator Chamber Systems Septic Design and Installation, Current Edition Because of the site conditions and gentle slope, a Chamber Trench System is recommended for this site. DESIGN FLOWS Number of bedrooms = 3, Maximum daily Flow (Qmax) = 1.5 X Ave. daily flow Qave = 3 bdrms x 2 persons/bdrm x 75 gallons/person/day = 450 gpd Qmax = 450 X 150% = 675 gpd SEPTIC TANK Volume = Qmax/24hrs x 30hrs Detention V = 1406 gallons (sized for potential future 2 bedrooms in basement) Use 1,500 Gallon (2 compartment) Valley Precast, Inc. or equivalent. Each compartment 750 gallons. ABSORPTION AREA Design percolation rate was calculated to be T = 10 MPI (minutes per inch) Based on Percolation rate of 10, and Course to Fine Sand (all cobbles to be removed), a Long Term Acceptance Rate (LTAR) of 1.2 GAL/Day/sf is shown in the table (CDPHE, pg 34) as acceptable. A = Qmax/1.2gpd/sf A = 675/1.2 = 562 sf As a double check, Using Eagle County Table 5; Absorption Area = 165 SF/bedroom or 495 SF, Page 1 of 4 For conservancy, this design to use 675 SF. INFILTRATOR CHAMBER SYSTEM IN SERIAL TRENCH DISTRIBUTION State Reduction for Trenches in Chamber System is 50% Square Feet per chamber is 10.0 (Quick 4) 30"x48" Final Absorption Area Required = 562 (0.50) = 281 sf Number of Chambers = Req'd Area/10.0 sf/chamber = 281/10 = 28 Chambers Recommend to install two (2) rows of 14 chambers. * Meets Manufacturer Minimum Recommendations Given site conditions.

The building sewer line from the house to the septic tank shall have a slope of/4 inch per foot (2%). Bends in the building sewer shall be limited to 45 degrees. 3. The septic tank shall be installed level. The tank shall have removable covers or manholes to within 8 inches of the finished grade, for inspection and cleaning. 4. Strip all topsoil in absorption bed area. Reuse for vegetative cover. 5. Excavate three (3) feet wide trenches where possible. The horizontal distance from' sidewall to sidewall between the trenches shall be a minimum of six (6) feet. NA. 6. The bottom and the sidewalls of the trenches shall be raked to eliminate smearing. 7. Assemble and install the Infiltrator Chambers in the trenches according to the manufacturer's recommendations. 8.
